Beatbot vs Cosmy: Corded vs Cordless Pool Cleaning Compared

Last updated: 23 July 2026 · Reviewed by the Poolbot UK product team

Cosmy (made by BWT, branded as "Cosmy the Bot") is a corded robotic pool cleaner — it plugs into a power supply via a floating cable rather than running on a battery. Beatbot's AquaSense 2 Ultra is fully cordless. For buyers who've found a corded cleaner's cable tangling or limiting where the robot can reach, going cordless removes that constraint entirely — no cable to manage, no fixed power point needed poolside.

Why buyers choose Beatbot over Cosmy

• No cable to manage. Cordless means no floating cable to tangle, no fixed power point required, and full freedom to move the robot anywhere in the pool.
• 4K AI camera and 3D mapping. 27+ sensors and a 4K AI camera build a real map of your pool for efficient, complete coverage.
• Water clarification built in. ClearWater™ natural clarification runs alongside physical cleaning — corded cleaners in this class are typically cleaning-only.
• 3-year warranty including the battery. Comprehensive UK-backed cover through Poolbot.

FAQs

Is Cosmy a corded or cordless pool cleaner?
Corded — Cosmy (made by BWT) connects to a power supply via a floating cable, unlike Beatbot's fully cordless design.

Do I need a power outlet near the pool for Cosmy?
Yes, corded cleaners like Cosmy need a nearby power point and cable management. Cordless robots like Beatbot don't.

Can I leave my Cosmy or Beatbot pool robot in the pool all the time?
No — Cosmy should be unplugged and stored when not cleaning, and Beatbot (cordless) needs removing to recharge between cleans. Neither is designed to be left in the pool permanently.
